Methods and apparatus for fencing and other structures

ABSTRACT

An improved method and apparatus for fencing and other outdoor structures that allow the structure to be changed or adjusted to modify the function, use or appearance of the structure. The structure can be adjusted into a selected position and releasably secured, or portions can be changed to modify the appearance of the structure. One aspect of the invention provides an accessible compartment in the structure to retain objects such as wires or other conduits, and allows for attaching selected objects to the structure.

REFERENCE TO RELATED APPLICATIONS

This invention relates to improvements in fencing systems and other outdoor structures, and more particularly relates to improved apparatus and methods of construction and use that allows the function and uses of the structure to be expanded and the construction, function and appearance of the structure to be selectively adjusted or changed to meet varying conditions of display and use. The invention is particularly suitable for use with fencing systems and other outdoor structures constructed from plastic materials such as PVC.

BACKGROUND INFORMATION

Fencing is commonly used in public and private locations to provide security by barring entry to the enclosed locations to provide privacy, or to improve the aesthetic appearance of the area. Most fencing has a fixed structural design. The fence remains permanently in essentially the same condition of appearance and use after it is installed in the desired location. Expensive maintenance is often required to preserve the original condition of the fence. Any substantial change in the function, use or appearance of the fence usually requires laborious activity such as reconstruction or painting. These prior fence constructions are not adaptable for performing additional functions and are not changeable or adjustable to provide the fence with a new or different use or appearance.

The arrangement and appearance of the fencing are particularly static or difficult to change when the fence is constructed of plastic materials such as polyvinyl chloride (PVC) and the like, a type of fencing that is becoming increasingly more prevalent. Plastic fencing typically must have a selected design and be manufactured, such as by molding or extrusion off-site at a factory. Only minor variations in the structure of the PVC or other plastic fencing can be accomplished at the site where the fence is to be installed to vary the use or appearance of the structure or adapt the structure to perform additional functions. Major changes in construction or design would require costly changes to the manufacturing process to create the different parts of a fence at the factory. The costs of storing or inventorying the number of different component parts having different functions or appearances is also very substantial.

The color and appearance of PVC or other plastic fencing or outdoor structures such as railing and decking are also difficult to change. Plastic materials are susceptible to degradation in sunlight due to the effect of ultraviolet rays. A plastic composition including titanium dioxide, a well known white pigment, provides a measure of protection from this potential degradation of the material when exposed to an outside environment. As a result, plastic fencing is usually a white or light color when treated with titanium dioxide or the like to minimize the possibility of degradation that may occur.

Some of these same disadvantages also arise with other outdoor structures, such as an outside rail or a deck that is constantly exposed to the elements. For example, it is difficult to change the function or appearance of an outdoor rail or deck component once it is installed in place, particularly if the structure is constructed from a plastic material such as PVC. Substantial costs would also be involved in attempting to manufacture and inventory the different components needed to selectively change the function or appearance of the structure.

Many current designs for fencing, railings and decks are also difficult to use with electrical wires, or fluid or air lines, and cannot readily accommodate the addition of useful attachments such as hangers for tools or utensils, work or support surfaces or the like. Such additional features and functions are particularly difficult to add to a fence or other structure manufactured at an off-site factory from a plastic material such as PVC. Many prior structures would have to be substantially reconstructed or replaced to be useful with electrical wires, fluid lines or various attachments.

BRIEF SUMMARY

This invention provides improved apparatus and methods of construction and use for fencing and other outdoor structures that allow the structure to be readily adapted to perform additional functions or changed to vary the use or appearance of the structure. In utilizing this invention the fencing, as an example, would not merely perform a static function such as dividing areas, providing privacy or barring entry to an area. With this invention the structure is readily adapted for additional features or functions and can be changed or adjusted easily for a different appearance or use. A fence incorporating this invention can be adapted or adjusted selectively to adapt to changes in lighting, such as changes in sunlight; to vary viewing or privacy conditions; to enhance security; to regulate ventilation or airflow; to collect solar energy; to adapt the structure to accommodate changes in seasons or holidays; to attach implements, tools or decorative items, to provide distribution channels for electrical wiring or air or water conduits, and to permit other desired adjustments or changes. The adjustable components of the fencing can be releasably locked into the selected position after the desired adjustment is made. In one aspect of the invention the improved structure provides a readily accessible compartment or pathway for receiving devices such as wiring or fluid lines, for storing items such as wires and hoses or for retaining items such as floral or garden arrangements, bird seed feeders or the like. The improved structure further includes an attachment feature that allows other components such as hangers or support structures to be easily attached.

The invention further provides apparatus and methods to readily change the appearance of the structure to suit particular needs or desires. The structure such as a fence, railing or deck component can be varied after installation by changing the color, texture or other appearance of the structure in a low-cost and efficient manner. By utilizing this invention with PVC or other plastic fencing, railing or decks can be changed from the traditional light or white colors to other shades of colors including darker colors and/or different textures. Changes in the appearance of the structure can be done to accommodate the changes in seasons or holidays, to match or coordinate with the colors of other structures such as adjacent houses, to improve visibility or safety, or to suit other needs or desires of the user.

In general the present invention relates to a method and apparatus for an outdoor structure that is capable of adjustment to vary the conditions of use. When used as a fence, this system includes fence rails for supporting a portion of the fence and movable fence members. Supporting structure support the fence members on the rails and allows them to be selectively adjusted to a plurality of positions and releasably locked into these selected positions. The invention provides a method and apparatus for altering or modifying the appearance of an outdoor structure such as a fence, railing or deck member. Each of the outdoor members include a structure having a selected face provided with a gripping element. A separate panel having a different selected appearance or color is engaged with the gripping element to modify the face of the outdoor structure. The member in accordance with invention further can define a compartment or pathway which is readily accessible and closable for receiving and storing a variety of objects.

Further objects and advantages of the present invention will become apparent from a description of the several embodiments as set forth in the following description and drawings.

DETAILED DESCRIPTION OF THE DRAWINGS AND THE PRESENTLY PREFERRED EMBODIMENTS

FIG. 1 illustrates a front elevational view of a portion of the fence 10 constructed in accordance with the present invention. The fence 10 includes vertical fence posts 12 and 14 and top and bottom horizontal fence rails 16 and 18. End caps 13 are placed on the upper ends of the supporting fence posts 12 and 14. In the preferred embodiments these components of the fence 10 are hollow and can be constricted from plastic materials such as polyvinyl chloride (PVC). The plastic members can be injection or blow molded, or extruded, and the like.

The Fence 10 includes a series of fence members or pickets 20 positioned between the top and bottom fence rails 16 and 18. The illustrated fence members 20 are vertical but the members can be arranged horizontally, diagonally or in other positions that may be desired. These fence members or pickets 20 can be selectively and readily adjusted to change the use, function, or appearance of the fence 10.

FIGS. 1 and 2 illustrate the fence members 20 being positioned in several different orientations for illustrative purposes. As seen in FIG. 1, each fence member 20 is movably supported on the upper fence rail 16 by an upper support structure 22 and supported on another rail 18 by an additional support structure 24. The illustrated fence includes two rails but it will be appreciated that additional rails can be provided on the fence.

FIGS. 3 and 4 illustrate the detailed construction of one embodiment for the upper support structure 22 for each of the fence members 20. As seen in FIG. 4, this upper support structure 22 includes a threaded fastener 26 which is secured by a friction fit, adhesive or other suitable means to an aperture provided in the top of the fence member 20. One end portion of the fastener 26 can take the form of a hex-head 26A and the other end of the fastener includes a threaded portion 26B. The fastener 26 can be provided with an aperture 28 which provides a channel through which components such as electrical wiring, fluid or air lines or the like can be extended to communicate between the inside hollow portions of the rail 16 and the fence member 20.

The fence rail 16 is provided with an aperture which receives the threaded end 26B of the fastening member 26, as illustrated in FIG. 4. The upper support structure 22 also includes a threaded locking nut 27 designed to engage with the threaded portion 26B of the fastener 26. The locking nut 27 is preferably hex-shaped so that it can be rotated manually or by using a conventional wrench or other tool to raise or lower the locking nut 27 on the fastener 26. Rotation of the member 20 is permitted when the locking nut 27 is spaced from the upper rail 16. The nut 27 may be used to lift the member 20 for rotation. This arrangement for the upper support structure 22 permits the fence member 20 to be rotated about a vertical axis by rotation of the fastener 26B within the aperture in the rail 16 and the resulting rotation of the fence member 20 with respect to the rail 16. The locking member, as shown in FIG. 4, is placed between the fence member 20 and the end rail 16 on the fastener 26.

Once the fence member 20 is positioned in the desired location through the rotation about the vertical axis, the locking nut 27 can be advanced on the threaded portion 26B of the fastener 26 against the rail 16 to releasably lock the fence member 20 in the selected position. If it is later desired to move the fence member 20 into a different selective position, the locking nut 27 can be rotated to release the fence member 20 and permit the member to once again rotate with respect to the rail 16. In this manner, the fence member 20 can be moved into a variety of orientations between the upper fence rail 16 and the lower fence rail 18 to adapt the fence for performing additional functions or to give the fence a different appearance.

FIGS. 5 through 9 illustrate a second embodiment for the upper support structure associated with each of the fence members 20. In this embodiment, the top end of each hollow fence member 20 is provided with an end cap 28. This end cap 28 is held in place by a friction fit, adhesive or other suitable means, and includes a tab 30 which can be used to move the fence member 20 for rotation. The tab 30 is preferably positioned on the inside face of the fence member 20 to enhance the security provided by the fence. The end cap 28 also carries a plunger housing 32 which receives a spring loaded plunger 34 having a compression coil spring 39, as shown in FIGS. 8 and 9. A pin 29 within the housing 32 retains the spring 39 in place. A base portion 36 has a circular element 38 and a shoulder 36A. The plunger 34 fits within the housing 32. The circular element 38 is rotatably positioned in an aperture in the lower part of the rail 16 and allows the member 20 to be rotated with respect to the rail. Flange 36B on the plunger base 36 retains the base 36 in place within the plunger housing 32. The shoulder 36B engages the top rail 16 so that the spring 39 urges the member 20 downwardly and releasably secures the member in a selected position by cooperating with the lower support structure 24 of the fence in accordance with this invention. As shown in FIG. 9, an aperture 35 can be provided in the center of the plunger assembly 34 to define a passage for wires or fluid lines or the like and thereby permit communication between the fence member 20 and the hollow rail 16. The fence member 20 can be formed to be hollow or have an opening to receive the wires, fluid lines or other objects.

FIGS. 10 through 12 illustrate a third embodiment for the upper support structure usable in the fence assembly in accordance with this invention. In this embodiment, the upper end of the fence member 20 is provided with a pivot pin 40 and the adjacent lower portion of the upper fence rail 16 is provided with a collapsible tensioning member 42. Preferably, the width of the tensioning member 42 is selected to be at least substantially the same as the width of the fencing member 20, as shown in FIG. 10. Alternatively, the tensioning member 42 can extend along the length of the rail 16 and can be attached to or formed on the rail. In this manner, the open space between the fence member 20 and the rail 16 is closed by the tensioning member 42. The member 42 will thus improve the privacy or protection provided by the fence 10. The lower portion of the tensioning member 42 is provided with an aperture 44 to receive the pin 40, as shown in FIGS. 11 and 12.

In accordance with this embodiment of the invention, the tensioning member 42 is constructed from a pliable material such as flexible plastic or elastomeric material. With this construction, the tensioning member 42 will flex and allow the fence member 20 to be moved against the biasing force of the tensioning member 42. When a moving force is applied to the fence member 20, the collapsible tensioning member 42 allows the member 20 to be rotated into the desired position. The member 42 then applies a tensioning biasing force to the member 20 to releasably secure the fence member 20 in the selected position.

FIGS. 13 through 15 illustrate a design for a second support structure 24 for each of the fence members 20 in accordance with the present invention. One component of the illustrated lower support structure comprises an insert 50 designed to be fixed by suitable means to the adjacent end of each fence member 20. The insert 50, as shown in FIG. 13, includes a pivot pin 52 positioned in the central portion of the insert. This pin 52 preferably has a tapered end 54 to facilitate the guiding of the pin 52 into place. The insert 50 further includes detent members 56 which are spaced about the periphery of the pin 52 as shown in FIGS. 13 and 14. These detent members 56 have a selected shape and are positioned around the pin 52 in a uniform pattern. In the illustrated embodiment shown in FIG. 14, the detent members 56 comprise a plurality of radial extensions spaced uniformly 60 degrees apart around the periphery of the pin 52. The pin 52 can also include an aperture 55 defining a passage for wire or fluid or air lines or the like which can be extended between for communication between the interior of the fence member 20 and the interior of the lower rail 18.

FIG. 15 illustrates alternative configurations for the lower rail 18 of the fence 10 in accordance with the present invention. The upper portion of the rail 18 is provided with an indexing and locking aperture 58A configured to receive the pin 52 and engage with detent members 56 on the lower support structure 50. Several alternative locking apertures 58B–E are also illustrated in FIG. 15. Each of these apertures 58A–E have a periphery with a selected pattern of detent surfaces 60A–E designed to cooperate with complementary detent members 56 on the lower support structure 50. The detents 56 can be arranged to be a selected number of degrees apart around the periphery of the pin 54 to be compatible with the corresponding shape of the aperture 58A–E and the detent surfaces 60A–E. Locking aperture 58A is compatible with the detent members 56 in the illustrated embodiment. The particular configuration for the detents 56 and the corresponding peripheral apertures 60 in the openings 58A–E can be chosen to provide a selected number of fixed positions for the adjustable fence member 20. The illustrated detents 56 and the apertures 60A are positioned 60 degrees apart. If the lower support structure is to be retrofitted to an existing fence the apertures 58A–E can be provided on a separate member that can be fastened to the fence rail.

The lower support structure 50 shown in FIGS. 13–15 is usable with any of the above-described embodiments of the upper support structure 22 to provide the fence 10 with support means which permits each fence member 20 to be adjustably positioned and releasably retained in a selected position with respect to the fence rails 16 and 18. If the infinitely variable support structure shown in FIG. 37 is used the lower support structure would be simplified as shown in FIG. 38.

If the upper support structure 22 shown in FIGS. 3 and 4 is used, the locking member 27 is rotated downwardly away from the upper fence rail 16. This will permit the fence member 20 to be raised and rotated with respect to the rail 16 and the lower rail 18 to the selected orientation. The member 20 rotates on the pin 52 until the member 20 is in the desired position, and the corresponding detent 56 is in place within the locking aperture 58A–E on the bottom rail 18. The locking member 27 then can be advanced on the thread 26B against the top rail 16 to limit the upward movement of the member 20 and lock the fence member 20 in the selected location.

If the embodiment for the upper support structure comprises the spring plunger 34 shown in FIGS. 5 through 9, or the collapsible tensioning insert 42 shown in FIGS. 10 through 12, the adjustment of the associated fence member 20 is accomplished by gripping the tab 30 on the fence member 20 and applying a moving force. This force will act against the bias of the spring loaded plunger 34 shown in FIG. 8, or against the collapsible tensioning member 42 shown in FIGS. 10–12 to permit the fence member 20 to be rotated into a selected position. Once the member 20 is in the desired position, release of the tab 30 will permit the bias of the plunger 34 or the collapsible tensioning member 42 to apply a biasing force to the fence member 20.

The lower support structure 50 on each fence member 20 operates in essentially the same manner as described above for each embodiment of the upward support structure. In each embodiment, the force of gravity and the weight of the fence member 20, assisted in some embodiments by a downward biasing force, will cause the detents 56 to be captured by the corresponding compatibly configured recesses 60A–E in the indexing and locking aperture 58A–E. The engagement between the detents 56 and the corresponding apertures 60A–E will releasably lock the associated member 20 in place. If the fence member 20 is to be adjusted further, the upward lifting force on the member 20 will disengage the detents 56 from the associated recesses 60A–E of the apertures 58A–E in the lower rail 18. The fence member 20 can then be rotated into a desired position and released. Gravity, assisted by a biasing force, will re-engage the detents 56 with the appropriate recesses 60A–E in the lower rail 18 to once again releasably lock the fence member 20 in a desired location.

The fence members 20 including the support structures described above therefore can be adjusted to change the function, use or appearance of the fence 10. If maximum security or privacy and minimum visibility through the fence are required, each of the fence members 20 can be positioned to be essentially parallel with the upper and lower fence rails 16 and 18. In the embodiment shown in FIGS. 10–12, the upper support structure including the collapsible tensioning member 42 will close the space between the upper portion of the member 20 and the upper rail 16 to further reduce the visibility through by the fence 10. Alternatively, each fence member 20 can be individually or collectively adjusted into any selected position with respect to the fence rails. For example, if a position of 60 degrees for the fence members 20 would be desired to respond to the effect of the sunlight or wind, provide privacy or perform other uses, one or all of the individual fence members 20 can be adjusted to that selected angle as described above and locked into place.

FIGS. 16–18 illustrate another aspect of the present invention which allows the components of the fence 10 such as the posts, rails or pickets or fence members to be varied in appearance or changed in function in a different manner. In this embodiment, each fence member 20 is provided on one or more of its faces with adhering or gripping elements. In the illustrated embodiment the gripping elements comprise a pair of channels 70, as clearly shown in FIGS. 16 and 17. These channels 70 are preferably formed in place when the member 20 is manufactured from a plastic material such as PVC. In FIGS. 16 and 17, each channel 70 is positioned along the edge of a face of the member 20 and forms a groove 72 along each edge. The gripping elements may also comprise grooves formed within the sides of the fence members 20. As shown in FIG. 17, a separate member such as a panel member 74 can be inserted into the grooves 72. The panel 74 will be removably held in place along each side of the fence member 20 by the channels 70. A suitable detent can be provided to prevent the panel 74 from sliding out of the channels 70.

The panel 74 is selected to have a color, texture or shape different from the color or texture of the associated fence member 20. If the fence member 20 is formed from a plastic material such as PVC, the usual color for the fence member is a light or white color. The changeable panel member 74 can be made from a material such as vinyl sheeting, and selected to change the color or texture of the member 20. The panel 74 also provides additional protection for the fence member 20 such as protection from ultraviolet rays.

Vinyl sheeting, such as used in vinyl siding for homes, is very useful for forming the separate panel members 74. Vinyl sheeting is readily available in a variety of colors and textures, and can be economically formed or sized to be positioned on outdoor structures of different dimensions. The use of vinyl sheeting to change the appearance or texture of an outdoor structure in accordance with this invention results in substantial economic and manufacturing benefits. The need to manufacture and inventory a substantial number of structures or components of varying colors and textures is reduced. Instead, the basic components of a structure such as a fence can be modified by providing a supply of readily available and economically manufactured vinyl sheets of different colors or textures.

FIG. 18 shows a fence system similar to the system shown in FIG. 1 but modified to include inserts 75A–75F on the faces of the fence members 20. For illustrative purposes, each insert 75A–75F is shown in FIG. 18 as having a different color, e.g., green, yellow, blue, orange, brown and silver, respectively. The fence panels could also comprise solar panels 90, as shown in FIG. 21, or panels having a selected texture. As noted above, these changeable panels can be selected for a variety of purposes, such as to change a portion of a fence to match the color of a nearby house, to reflect holidays or changes in seasons for providing the fence with decorative patterns, to display messages, to collect solar energy, or for other uses.

FIGS. 19 through 21 illustrate further embodiments of the system for changing the appearance or function of the fence 10 in accordance with this invention. In FIG. 19, a generally u-shaped channel member 80 is designed to be retrofitted onto an existing fence member 20. The channel member 80 can be adhered to the face of the member 20 by a suitable adhesive, or held in place by other forms of fasteners. The channel member 80 defines a channel 82 at each edge of the member 20 which creates grooves 84.

FIG. 20 illustrates the fence member 20 in FIG. 19 having a channel member 80 joined to its face and further having an insert member 89 positioned in place in the grooves 84. This channel member 80 and/or the insert member 89 can have a different color, texture or shape as compared to the appearance and material forming the fence member 20. Each fence member 20 including the channel member 80 can be changed by selecting the inserts 89 to suit the particular use or appearance desired for the fence member. Other inserts such as the panels 74 or the solar panel 90 shown in FIG. 21 can be inserted within the channel member 80.

FIG. 21 illustrates a further aspect of the present invention where the structure inserted onto the face of the fence member 20 comprises a solar energizing element or laminate such as a solar panel 90. In this embodiment each of the fence members 20 that carry a solar panel 90 will be capable of collecting solar energy from the sunlight. The above-described upper and lower adjustable supports for each fence member 20 can be used to position the fence members 20 to maximize the effectiveness of the solar panels 90 in response to the changes in seasons, or to accommodate other changes in environmental conditions. Suitable conducting wires or fittings and connectors can be included in the structure to distribute the energy collected by the solar panels 90. For example, electrical wires 91 can be connected to the solar panel 90 and extended through suitable holes in the fence member 20. The wires 91 can be connected to other wires, fittings or connectors in the fence system

The embodiments of the invention shown in FIGS. 16–21 can be used to change the appearance of the fence member 20 for a variety of purposes. As an example, the structure can be used to change a normally white fence to a darker color that matches or complements the color of the associated house or other structure. The fence member 20 can be changed in appearance to reflect the seasons or holidays or other events important to the user. Alternatively the panels 74 can added to the fence member 20 to carry a message such as an advertisement. Other functions, such as the collection of solar energy by the solar panels 90, can be added to the fence.

The embodiments of the invention illustrated in FIGS. 16 through 21 can also be used in other outdoor structures such as railings or deck members or the like to change the appearance, color, texture or function of the structure. The insert panels 80 and 90 can be used to produce the desired change to the rail or the deck member.

FIG. 22A illustrates an improved fence rail 100 which can be incorporated into a fence. This fence rail 100 can be used as a replacement for the top fence rail 16 or the bottom fence rail 18. The fence rail 100 can be made from plastic such as PVC. The rail 100 is manufactured, such as by molding or extrusion, to have multiple compartments such as a lower compartment 102 and an upper compartment 104. Both of these compartments 102 and 104 preferably extend for the length of the rail 100. In an alternative embodiment the compartment 104 can include a vertical divider 105, as shown in dotted lines in FIG. 22A. This divider 105 forms a plurality of compartments and adds strength to the rail. One side of the lower compartment 102 in this embodiment is provided with an access opening 106. This access opening 106 is also formed into the rail 100 and also preferably extends for the length of the rail. The access opening 106 provides the fence rail 100 with an opening for receiving attachment devices such as the hanger 108 or the like, as shown in FIG. 22A. The hanger 108 or other suitable fastening device can be inserted within the access opening 106 and used to support a variety of items on the fence rail 100. The hanger 108 or other suitable devices can be received within the opening 106 for supplying decorative items, outdoor gardening or cooking implements, support surfaces for flower pots, garden hose supports, and the like.

The access opening 106 in the rail 100 further provides access to the lower compartment 102. The compartment 102 therefore can receive through the opening 106 additional items such as electrical wires or conduits that would desirably be contained within the compartment 102 along the length of the rail 100.

The upper portion of the rail 100 as illustrated FIG. 22A includes an openable top 110.

The access opening 106 in the fence rail 100 permits attachments such as the hanger 108 to be added to the fence. The access 106 also would permit items such as electrical wires to be placed within the lower compartment 102 of the rail 100, as shown in FIG. 22A. Similarly, the openable top portion 110 of the fence rail 100 provides ready access to the upper compartment 104. The compartment 104 could also be provided in another lower rail of the fence. In this manner, items can be stored in a rail of the fence, or the rail compartment 104 can be used to place items such as electrical wires, water or air lines along the length of the rail 100.

In FIG. 28, the top fence rail 100, having a construction such as shown in FIG. 23, has a top 124 which permits a compartment 122 which could be selectively opened and closed. This compartment 122 in this embodiment contains a series of insertable containers 112 adapted to support items such as floral arrangements, or bird seeders, or the like. A plurality of these containers can be stationed along rail 100 in the compartment 122 to provide the fence structure with containerized materials such as floral arrangements, bird feeders. Insect repellants, net systems or the like,

FIGS. 29–31 illustrated further the embodiment of the invention where an existing fence structure is retrofitted to have a rail including an accessible compartment. In this embodiment a fence system including fence members 20 supported on upper and lower rails 16 and 18 by fence post 12 and 14 is provided with a retrofit elongate rail 120. As shown in FIGS. 29–31 rail 120 is extended laterally along the fence system and supported by the fence posts 12 and 14. Alternatively, the rail 120 can be supported by the preexisting fence rail 16. This fence rail 120 is similar to the rail having an accessible compartment such as shown in FIGS. 22A–26. The rail includes a movable cover 122 which can be opened and closed to provide ready access to the compartment 124 within the rail. As described above, the compartment provided in the rail 120 can receive a variety of objects such as wires, fluid lines, floral containers and the like.

The embodiment of the fence system shown in FIGS. 32 and 33 provide the fence with a device to raise or extend the fence to suit particular needs or functions. For example, the extension mechanism 130 can be used if the area near the fence is being used for a game to keep balls or other items within the fenced area. Additional screening can also be used in place of the net 132 to enhance the privacy of the fence.

FIGS. 34 and 35 show a universal attachment mechanism that can be incorporated into the fence system of this invention. In this embodiment, the compartment 104 within the fence rail 100 (with top 110 being removable if desired) is used to receive and support an attachment mechanism 140. The mechanism 140 can be dimensioned to fit securely within the compartment 104 and can extended for a selected length along the rail 100. Grooves or retaining surfaces 142 can be provided to engage with the upper portions of the rail 100 and assist in securing the mechanism 140 in the rail. The upper portion of the mechanism 140 can be dimensioned to extend out of the compartment 104 in the rail 100, as seen in FIGS. 34 and 35 to support attachments.

Fastening grooves or recesses 144, 146 and 148 are provided in the top portion of the mechanism 140. These recesses 144, 146 and 148 can be different sizes or shapes and are designed to receive corresponding fastening elements on items which can be connected to and supported by the fence rail 100. For example, a working surface or table 150 can be joined in the recess 146 and a support hook 152 can be connected in the recess 148. Other items with compatible fastening elements can be added to the fence rail 100 by use of this universal attachment mechanism 140.

FIG. 36 illustrates a modified rail that also can be used when it is desired to perform functions such as collect solar energy, display signs or the like on the rail or change the color or texture of the rail. FIG. 36A shows a perspective view of a triangular rail 160 which includes two angled upper surfaces. Gripping elements 162 are positioned on each corner of the rail 160 for receiving panels 164. These panels 164 can be made to have a selected color or texture, or can carry a message such as an advertisement. In addition panels 164 can comprise solar panel or laminate to collect solar energy. The angled upper surfaces of this triangular rail 160 makes the panels very visible and positions a solar panel 164 for more exposure to the sun.

FIGS. 37, 37A and 38 illustrate a modified support structure for use in an adjustable fence in accordance with this invention. As seen in FIG. 37 one end of a fence member 20 is provided with an infinitely variable support structure 170 including a pivot pin 172. One end of the pin 172 is fixed in the fence member 20 by a head 174. The other end extends into a positioning clamp assembly 176. The clamp assembly 176 pivotally receives the pin 172 and is fixed within the adjacent fence rail 16. A flexible clamping ring 178 on the clamping assembly surrounds the pin 172 and includes a fastener such as the threaded bolt 180. This ring 178 is connected to or integral with the assembly 176. FIG. 38 shows a suitable pivot pin 182 that is positioned in the other end of the fence member 20 and allows the member to rotate with respect to the associated rail.

The arrangement for the variable support structure 170 shown in FIGS. 37, 37A and 38 can be used to move the fence member 20 into a plurality of selected positions with respect to the rail 16 by pivoting the member about the pins 172 and 182. Once the member 20 is in the desired position the bolt 180 can be advanced to tighten the clamp 178 around the pin 172. Since the clamp 178 is fixed to the rail 16 through the clamp assembly 176, this clamping force will releasably secure the fence member in the selected position. An infinite number of positions are possible for the member 20 as a result of this embodiment for the support structure.

As described above, the support structures for the fence members 20 include apertures that can be used in combination with the compartments 102 or 104 in the top rail 100 to connect the fence members 20 with electrical wiring, or with conduits for receiving water or the like. The fence members 20 can further include inserts, such as the panels 74 or the solar panels 90 which can be connected to wiring in the rail 100. The functions of the fence 10 are substantially enhanced by the combined use of the features of this invention

The features and functions of the improved rails illustrated in FIGS. 22 through 26 can be adapted for use with other structures, such as hand rails or decking. Such structures would thereby be provided with accessible compartments and passageways for receiving items, such as wires or conduits, which enhance the function of the structure.
